hi guys,
on my vox ac15 i have a normal channel with high and low inputs, and a top boost channel with with high and low inputs,would you guys ever patch lead the input??? or have a ABY box into both channels??? how would you guys use these inputs to get the best sound for me, i run my amp clean and get dirt up with drive pedals,

all the best, bluesfloyd
 
Re: normal/ top boost channel

When I played around with an AC30 for a while, I got my favorite sound (so far) by going into the top boost, cutting the bass heavily, splash some treble in, and use the tone cut to taste. Then run both the preamp hot and volume hotter. With that, I had a nice and thick midrange, still-cutting highs, and I had complete control over the gain with just my volume control. I was using a single humbucker-single volume guitar, and I could get a great lead and bright but-hard-hitting rhythm sound, that cleaned up beautifully with the volume around half. That's what I personally like about the AC series, it has a bunch of sounds at the disposal of your guitar's controls. The AC series is really versatile and usable in that regard (at least, that's what my opinion says).

Unfortunately I didn't have a treble booster on me at the time, so I couldn't do the classic "dime the normal channel and use with a treble booster". Next time. The ABY box also sounds like a good idea.

What ac 15 so you have? I had one and it only had one input.

Edit: one input for each channel

Re: normal/ top boost channel

I'm going to assume we're talking about a Normal channel using a 12AX7, not the EF86 as used in the original AC15.

Way back in the early '70s i owned a couple of AC30s and I found the normal channel too dark and the Top Boost channel too bright, so I used a short cable to patch the guitar into both channels, and then set the blend using the two volume controls. But then i started to notice almost any time i saw someone else using an AC30, I'd see the little loop of cable sticking up from the control panel, and i soon came to realise that other AC30 users had also discovered this trick.

It always seemed to sound good to me (and others), but years later i came to understand that the two channels are out-of-phase with each other. But it's worth trying and hearing for yourself, with your guitar and playing. If you wanted to get the two channels in phase, one simple way of doing it would be to have the guitar signal going into one of the channels via a one-transistor booster (Rangemaster-style, EH LBP1 style, etc.) The single transistor will flip the phase 180 degrees, thus getting it back in phase with the input of the other channel.
